beta.sessions.events.stream_events(session_id, **kwargs) -> Stream<BetaManagedAgentsStreamSessionEvents>

GET/v1/sessions/{session_id}/events/stream

流式传输事件

Parameters

session_id: String⁠Path

event_deltas: Array[BetaManagedAgentsDeltaType]⁠Query

When set, this connection also receives streaming deltas (event_start, event_delta) while an event is being produced, before the event itself arrives. Deltas are best-effort; when the final event is produced it carries the complete content. A model request that ends early (an error or interrupt) produces no final event — its terminal span.model_request_end closes the preview. Accepts one or more event types to preview and may be repeated: agent.message streams content_delta fragments; agent.thinking is start-only — a signal that the agent has begun extended thinking, concluded by the agent.thinking event itself. Only previews of the requested event types are sent.

One of the following:

:"agent.message"

:"agent.thinking"

workspace_id: String⁠Header

Optional header to select the Workspace for this request. The value is a Workspace ID (for example, wrkspc_011CZkZaBF1tNoB5wlCeusgy).

Only needed for credentials that can act on more than one Workspace. A credential that belongs to a specific Workspace may omit it; if sent, it must match that Workspace.

Returns

type BetaManagedAgentsStreamSessionEvents = BetaManagedAgentsUserMessageEvent | BetaManagedAgentsUserInterruptEvent | BetaManagedAgentsUserToolConfirmationEvent | 41 more

Server-sent event in the session stream.
